A colorful protein model that will engage your students in discussions about how a protein can assemble into quaternary structure to perform specific functions.

Hemolysin is a protein produced by the bacteria Staphylococcus aureus.
Seven subunits of hemolysin assemble into a heptamer complex that embeds
itself into the membrane of a red blood cell. Each subunit contributes 2
strands to a 14-stranded beta-barrel that is inserted into the membrane
to create a hole. Hemoglobin protein then leaks out of the red blood
cells, making the iron available to the bacteria to support their
growth.

Each of the 7 subunits in this 3-D protein model of hemolysin is
displayed in a alpha carbon backbone format and colored differently
(red, light green, orange, blue, light blue, purple, and green) to help
your students see the individual subunits.

This 3.5'' model is made of plaster by rapid prototyping and should be
handled with care. Mini models will break if dropped, held tightly or
handled roughly. Its PDB file is 7AHL.pdb.
